  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[First Embodiment]
As shown in FIG. 1, the digital camera to which the first embodiment of the present invention is applied includes a lens 10, a CCD area sensor 11, a preprocess circuit 12, an A / D conversion circuit 13, an image signal processing unit 14, and a recording unit 15. , A display control unit 16, a display unit 17, a sound input unit 18, an operation unit 19, and a camera control unit 20.

  Here, the operation unit 19 is not particularly illustrated, but in addition to the power switch, an operation member related to photographing such as a zoom button and a shutter button, and an operation member for performing various settings such as a menu button and a cursor movement button. And a mode button for instructing an operation mode such as shooting or reproduction. Of course, the mode button is not provided as an independent operation button because it is switched from the menu according to the operation of the menu button.

  In response to turning on the power switch of the operation unit 19, the camera control unit 20 starts the operation of each unit of the digital camera.

  The lens 10 is a photographing lens for imaging light from the subject, and the camera control unit 20 controls the focusing operation and zooming operation of the lens 10. The light image incident from the lens 10 is formed on the CCD area sensor 11 through a color filter (not shown). The image signal output from the CCD area sensor 11 is subjected to predetermined processing such as amplification, waveform shaping, noise removal, and the like by a preprocess circuit 12 configured by an analog circuit, and then converted to digital data by an A / D conversion circuit 13. It becomes. The image data converted into digital data is subjected to various image processing by the image signal processing unit 14.

  This image processed image data is converted by the display control unit 16 into low-resolution image data that matches the resolution of the display unit 17 such as a liquid crystal display disposed on the back of the camera, and is displayed on the display unit 17. Thus, so-called live view display is performed. Further, the focusing operation is controlled by the camera control unit 20 using the digitalized image data.

  When the shutter button of the operation unit 19 is operated, the camera control unit 20 controls the recording unit 15 to record the image data processed by the image signal processing unit 14 on the recording medium as an image file. This recording medium may be a built-in and fixed medium in the digital camera, or a recording medium that is detachable from the digital camera.

  When the playback mode is designated by the operation of the operation unit 19, the camera control unit 20 controls the recording unit 15 to read out the image file recorded on the recording medium and display the image data as a display control unit. 16 is reproduced and displayed on the display unit 17. In addition to displaying on the display unit 17 included in the digital camera, the digital camera is connected to an external display device such as a monitor device, and image data is output from the display control unit 16 to the external display device for display. It is also possible.

  At the time of this reproduction display, the camera control unit 20 measures the time during which the image data is displayed, that is, the viewing time of the image data, and the result is displayed as display information by the recording unit 15 in association with the image file of the image data. Record on a recording medium. That is, the camera control unit 20 functions as a display information acquisition unit that acquires display information relating to the display time of the image data, and the recording unit 15 records the acquired display information on the recording medium in association with the displayed image data. It functions as a recording means.

  In addition, the camera control unit 20 uses a sound input unit 18 composed of a microphone, an A / D conversion circuit, and the like at the time of the above-mentioned reproduction display. The conversation information relating to the conversation is acquired, and the recording unit 15 associates the conversation information with the image file of the image data and records it on the recording medium. In other words, the camera control unit 20 functions as interest level information acquisition means for acquiring interest level information regarding the level of interest in the image data of a plurality of persons, and the recording unit 15 associates the acquired interest level information with the image data being displayed. Function as recording means for recording on the recording medium.

  As described above, the recording unit 15, the sound input unit 18, and the camera control unit 20 constitute the image recording apparatus according to the first embodiment of the present invention.

  The camera control unit 20 classifies the image data recorded on the recording medium based on the display information and interest level information recorded on the recording medium, as will be described in detail later. That is, the camera control unit 20 functions as a classification unit. As described above, the recording unit 15, the sound input unit 18, and the camera control unit 20 constitute the image classification device according to the first embodiment of the present invention.

  In addition, when a mode for displaying a plurality of image data recorded on the recording medium is designated by the operation of the operation unit 19, the camera control unit 20 changes the display method of the plurality of image data according to the classification result. The display control unit 16 is controlled so as to be changed and displayed on the display unit 17. That is, the display control unit 16 and the display unit 17 function as display means for displaying a plurality of image data recorded on the recording medium, and the camera control unit 20 includes a plurality of recording data recorded on the recording medium according to the classification result. It functions as display method changing means for changing the display method of image data. As described above, the recording unit 15, the display control unit 16, the display unit 17, the sound input unit 18, and the camera control unit 20 constitute the image classification device according to the first embodiment of the present invention.

  As a method for recording on the recording medium associated with the display data of the display information and the interest level information by the recording unit 15, as shown in FIG. 2A, each image file 152 is stored in the recording medium 151. Apart from that, a method of recording display information and interest level information as the information table 153 is conceivable. In this case, the file ID recorded in the header 154 constituting the image file 152 can be associated.

  Alternatively, as shown in FIG. 2B, display information and interest level information may be recorded in the header 154 of the image file 152. Further, although not specifically shown, it can be embedded in the image data 155 by a technique such as digital watermarking.

  Next, the display information recording operation will be described. When the playback mode is designated by the operation of the operation unit 19, the camera control unit 20 performs display information acquisition processing as shown in FIG.

  That is, first, the recording unit 15 is controlled to read one image file 152 instructed to be reproduced from the recording medium 151, and the image data 155 is reproduced and displayed on the display unit 17 via the display control unit 16. (Step S11). Then, an elapsed time (image switching time) since the start of the reproduction display is measured by a built-in timer (not shown) (step S12). The reproduction display and the image switching time measurement are continued until the reproduction of the image file 152 is finished or a reproduction instruction for another image file is given by the operation of the operation unit 19 (step S13). When the reproduction display of the image file 152 is completed, the measurement result of the image switching time is acquired as display information, and is recorded in the recording medium 151 in association with the image file 152 by the recording unit 15 (step S14). .

  Next, the recording operation of the interest level information will be described. Here, the conversation information, which is the interest level information, is the conversation amount of a plurality of surrounding people who are viewing the image. This is because in many cases, the amount of conversation is considered to be proportional to the degree of interest in the displayed image data.

  When the playback mode is designated by the operation of the operation unit 19, the camera control unit 20 performs an interest level information acquisition process as shown in FIG. That is, first, the recording unit 15 is controlled to read out the image file 152 instructed to be reproduced from the recording medium 151, and the image data 155 is reproduced and displayed on the display unit 17 via the display control unit 16 (step S1). S21). And the conversation after starting the reproduction | regeneration display is acquired from the sound input part 18 (step S22), and the amount of conversation is measured (step S23). That is, the amount of conversation is measured by converting speech into text and counting the number of characters. The reproduction display and the conversation amount measurement are continued until the reproduction of the image file 152 is finished or a reproduction instruction for another image file is given by the operation of the operation unit 19 (step S24). When the reproduction and display of the image file 152 is completed, the conversation amount measurement result is acquired as interest level information, and is recorded in the recording medium 151 in association with the image file 152 by the recording unit 15 (step S25). .

  Although the display information acquisition process and the interest level information acquisition process have been described separately, it is needless to say that the camera control unit 20 can simultaneously acquire the display information and the interest level information.

  Next, image data classification processing based on display information and interest level information recorded on the recording medium 151 and processing for changing a plurality of image data display methods according to the classification results will be described. Here, as a method of displaying a plurality of image data recorded on the recording medium 151, a thumbnail display in which reduced images of a plurality of image data recorded on the recording medium 151 are displayed in a list will be described as an example.

  When thumbnail display is designated by the operation of the operation unit 19, the camera control unit 20 performs an image reproduction process as shown in FIG. That is, first, regarding one image file 152 recorded on the recording medium 151 by the recording unit 15, whether display information has been acquired, that is, display information recorded in association with the image data 155 of the image file 152 is displayed. It is determined whether or not there is (step S31). Here, if the display information has been acquired, regarding the image file 152, there is further interest level information recorded in association with whether or not the interest level information has been acquired, that is, in association with the image data 155 of the image file 152. Whether or not (step S32).

  If both the display information and the interest level information have been acquired, the image data 155 of the image file 152 is classified based on the information, and the classification result is stored or recorded in an internal memory (not shown). Recording is performed on the medium 151 (step S33). This classification is based on the relationship between display information (display time) and interest level information (conversation volume) as shown in FIG. 6 (A), for example, to four classification levels L1 to L4 by respective threshold values Th1 and Th2. Classify.

  If either the display information or the interest level information is not acquired, the image data 155 of the image file 152 is classified into a default classification level, and the classification result is stored in an internal memory (not shown). Or it records on the recording medium 151 (step S34).

  Then, according to the stored or recorded classification level, the display method of the reduced image of the image data 155 of the image file 152 generated by the display control unit 16, here, the size of the reduced image is changed (step S 35). The reduced image is displayed on the display unit 17 (step S36).

  By performing such an image reproduction process on the number of image files that can be displayed as a list on the display unit 17, reduced images whose sizes have been changed are displayed in a list as shown in FIG. 6B. The

  In this case, as shown in FIG. 6A, the size of the reduced image is an image in which the display time is long and the amount of conversation data is large (classification level L4), and the display time is short and the conversation amount is small. This is an example of reducing the size of the classification level L1).

  How to classify from the display time and the amount of conversation and how to change the size of the reduced image are shown in FIGS. 7A and 7B by the operator operating the operation unit 19, for example. As shown, it can be determined freely. That is, the operation unit 19 and the camera control unit 20 function as a classification level setting unit that sets a classification level based on display information and interest level information, and set a relationship between a classification result and a changed display method. Functions as a means. It is also assumed that the operator can arbitrarily set the default classification level. These settings are stored in an internal memory (not shown) of the camera control unit 20 and used. As a result, it is possible to classify and display according to the preference of the operator and the form that is easy to see.

  As described above, according to the first embodiment, during the display of the image data, the information regarding the display time of the image data and the degree of interest in the image data of a plurality of persons including the operator and the surrounding viewers are displayed. Since the conversation volume as the conversation information, which is information related to the information, is acquired and recorded in the recording medium 151, information that can classify the image data by reflecting the reaction of not only the operator but also the surrounding people is associated with the image data. An image recording apparatus capable of recording can be provided.

  Further, by classifying image data based on such information, it is possible to provide an image classification device that can classify image data by reflecting the reactions of people around the operator.

  Furthermore, by using the results classified in such a manner, it is possible to change the size of each reduced image when displaying a plurality of image data as thumbnails to reflect the reaction of the surrounding people, that is, the interest. An image display device can be provided.

  In the image reproduction process shown in FIG. 5, the example of changing the size of the reduced image when both the display information and the interest level information are acquired has been shown, but either the display information or the interest level information is displayed. Even when one piece of information is acquired, the image size may be changed and displayed.

  In addition, the size of the reduced image has been explained as an example of changing the display method according to the classification. However, what kind of things are changed such as changing the brightness instead of the size or adding frames with different thicknesses and colors? It does not matter. Of course, the size, thickness, and type of frame may be arbitrarily combined. In this way, by performing the identification display that can identify the difference between the classification levels, it is possible to present the responses of the plurality of persons including the operator to each image data in an identifiable manner.

  In addition, the conversation amount is described as an example of the conversation information that is the interest level information. However, the voice volume during conversation (the higher the interest level, the louder the voice) and the voice tone (the higher the interest level, the higher the voice tone). Can be converted into numerical values as conversation information. Furthermore, the contents of the conversation made into text are discriminated by a matching table etc., and for example, “Good” is scored by a method such as adding a positive score, “Not in focus”, etc., adding a negative score, The scoring result can also be used as conversation information. Of course, the conversation volume, voice volume, voice tone, and conversation content may be arbitrarily combined. In this way, by using conversation information as interest level information, it is possible to perform classification that reflects the reaction of each person including an operator to each image data. In addition, since the conversation input as sound is not recorded but is numerically recorded as the conversation amount, the recording capacity can be reduced.

[Second Embodiment]
In the first embodiment, an example has been described in which conversation information relating to conversations between a plurality of people is acquired as interest level information. However, interest level information is not limited to such conversation information.

  For example, by using a gaze detection method as disclosed in Japanese Patent Application Laid-Open No. 2004-213486, gaze information relating to gazes of a plurality of surrounding people can be acquired as interest level information.

  In this case, the interest level information acquisition process when the reproduction mode is designated by the operation of the operation unit 19 is as shown in FIG.

  That is, the camera control unit 20 first controls the recording unit 15 to read the image file 152 instructed to be reproduced from the recording medium 151, and the image data 155 is not shown via the display control unit 16. It is played back by the external display device (step S21). This is because the line of sight is detected from the captured image data, and the back side of the digital camera on which the display unit 17 is arranged cannot be directed toward a plurality of people including the operator.

  Then, the line of sight of a plurality of people viewing the image data displayed on the external display device is detected from the image data from the image signal processing unit 14 (step S26), and the total gaze time of each person is measured. (Step S27). This is because the gaze time is considered to be proportional to the degree of interest in the displayed image data. Therefore, in this embodiment, it is necessary to arrange the digital camera in a state in which a plurality of people including the operator are included in the visual field and in the vicinity of the display surface of the external display device.

  The reproduction display and the gaze time measurement continue until the reproduction of the image file 152 is finished or another image file is instructed by the operation of the operation unit 19 (step S24). When the reproduction and display of the image file 152 is completed, the measurement result of the gaze time is acquired as the interest level information, and is recorded in the recording medium 151 in association with the image file 152 by the recording unit 15 (step S28). .

  Since other than that is the same as that of the said 1st Embodiment, the description is abbreviate | omitted.

  As described above, according to the second embodiment, during the display of the image data, the information regarding the display time of the image data and the degree of interest in the image data of a plurality of persons including the operator and the surrounding viewers are displayed. Since the gaze time as the line-of-sight information, which is information related to the image data, is acquired and recorded in the recording medium 151, information that can classify the image data by reflecting not only the operator but also the reactions of surrounding people is associated with the image data. An image recording apparatus capable of recording can be provided.

  Further, by classifying image data based on such information, it is possible to provide an image classification device that can classify image data by reflecting the reactions of people around the operator.

  Furthermore, by using the results classified in such a manner, it is possible to change the size of each reduced image when displaying a plurality of image data as thumbnails to reflect the reaction of the surrounding people, that is, the interest. An image display device can be provided. The display in this case may be performed on either the display unit 17 of the digital camera or an external display device.

  Note that it may be combined with the conversation information as described in the first embodiment. In this case, classification may be performed based on the three-axis coordinates of the display information, the line-of-sight information, and the conversation information, or the line-of-sight information and the conversation information may be added or weighted to perform classification based on the two-axis coordinates of the display information. It is also possible to do so.

[Third Embodiment]
In the first and second embodiments, as a method for displaying a plurality of image data recorded on the recording medium 151, a thumbnail display in which reduced images of the plurality of image data recorded on the recording medium 151 are displayed in a list is shown as an example. As described above, the display method is not limited to such thumbnail display.

  For example, as such a display method, a slide show display in which a plurality of image data recorded on a recording medium is switched and displayed in time series is known.

  When a slide show display is designated by the operation of the operation unit 19, the camera control unit 20 performs an image reproduction process as shown in FIG.

  That is, first, regarding one image file 152 recorded on the recording medium 151 by the recording unit 15, whether display information has been acquired, that is, display information recorded in association with the image data 155 of the image file 152 is displayed. It is determined whether or not there is (step S31). Here, if the display information has been acquired, regarding the image file 152, there is further interest level information recorded in association with whether or not the interest level information has been acquired, that is, in association with the image data 155 of the image file 152. Whether or not (step S32).

  If both the display information and the interest level information have been acquired, the image data 155 of the image file 152 is classified based on the information, and the classification result is stored or recorded in an internal memory (not shown). Recording is performed on the medium 151 (step S33). If either the display information or the interest level information is not acquired, the image data 155 of the image file 152 is classified into a default classification level, and the classification result is stored in an internal memory (not shown). Or it records on the recording medium 151 (step S34).

  Then, according to the stored or recorded classification level, the display method of the image data 155 of the image file 152 generated by the display control unit 16, here, the display time of the image data is changed (step S 37), and the display unit 17. Alternatively, image data matching the resolution is displayed on the external display device (step S38). Thereafter, the image data is displayed until the changed display time elapses (step S39).

  Such an image reproduction process is sequentially performed on the plurality of image files 152 recorded on the recording medium 151, whereby a slide show display is performed.

  Since other than that is the same as that of the said 1st Embodiment, the description is abbreviate | omitted.

  As described above, according to the third embodiment, during the display of the image data, the information regarding the display time of the image data and the degree of interest in the image data of a plurality of persons including the operator and the surrounding viewers are displayed. Since the information on the recording medium 151 is acquired and recorded in the recording medium 151, the image recording can be recorded in association with the image data so that the image data can be classified by reflecting the reaction of not only the operator but also the surrounding people. An apparatus can be provided.

  Further, by classifying image data based on such information, it is possible to provide an image classification device that can classify image data by reflecting the reactions of people around the operator.

  Furthermore, by using the results classified in such a manner, it becomes possible to change the display time of each image data when displaying a plurality of image data as a slide show to reflect the reaction of the surrounding people, that is, the interest. An image display device can be provided.

  In the image reproduction process shown in FIG. 9, an example in which the display time is changed when both the display information and the interest level information are acquired is shown. However, either the display information or the interest level information is displayed. Even when the image data is acquired, the display time of the image data may be changed and displayed.

  Further, the interest level information may be updated by executing the interest level information acquisition process during the slide show display.

  Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications and applications are naturally possible within the scope of the gist of the present invention.

  For example, although the above embodiment has been described by taking the case of being mounted on a digital camera as an example, an image recording apparatus that records image data, display information, and interest level information on a recording medium, and a recording medium on which such information is recorded As an image classification device that reads out information from the image data, classifies the image data, and appends the classification result to the recording medium, reads the classification result from the recording medium, and changes the display method of the image data based on the classification result, It is also possible to configure each independently.

  It is also possible to realize the above functions by supplying a software program for realizing the functions of the image recording device, the image classification device, and the image display device to a computer and executing the program by the computer.
